Cadillac XTS rear shock absorbers leaking, dealer noted black oil presence on Cadillac XTS

Some Cadillac XTS owners report experiencing issues with leaking rear shock absorbers, often accompanied by the presence of black oil. This leakage typically indicates failed internal seals, necessitating inspection and potential replacement. While some owners note that trace amounts of oil may not confirm a serious leak and could be considered normal seepage, those who feel a deterioration in ride quality are advised to pursue replacement, particularly before their warranty expires. Additionally, many owners may not immediately recognize the gradual loss of dampening ability in their shock absorbers, which can affect ride smoothness over time. Various factors, including dirt, worn seals, and rough terrain, can contribute to these leaks, leading to imbalanced tires and a floating sensation while driving. The seal at the top of the shock absorbers is particularly crucial for preventing oil spillage and maintaining proper lubrication; if it fails, it can render the shock absorbers ineffective. Therefore, it is essential for owners to address these concerns promptly to ensure optimal vehicle performance and safety.
